Molds on Air Vents

Molds on Air Vents

Mold is a naturally occurring chemical or fungus that can be found both outside and within your home or building. If you discover mold on your air vents, get rid of it as soon as possible. When your family’s health is neglected, it can be dangerous. We can, however, educate you how to get rid of it and how to prevent it. 

Causes of Molds on Air Vents

Mold on air vents and ducts is caused by a variety of factors:

Moisture

When there is moisture inside the ductwork, mold in the air vents is most likely to grow. On hot days, the moisture in the air can condense inside the air vents as cool air travels through them. When you sip an icy beverage, water beads up on the outside of the glass, the same process is at work. Mold can grow inside vents if there is moisture present. Mold thrives in humid environments, and because air vents are humid, you should expect to discover mold in them.

 

Ambient Temperature

Mold spores are usually airborne, meaning they propagate through the air. Spores can infiltrate the duct system by blowing in from another room or from the outside. However, the appropriate conditions are required for the spores to form. If the conditions are ideal, a single mold spore can blow into your home and start to grow into a colony. Mildew spores thrive in warmer, more humid settings.

 

Inadequate Ventilation

Although you may believe that your air vents are ideal for ventilation, this isn’t always the case. If you have poor ventilation due to a blockage, dust, leaks, or insufficient exterior vents, the air will not circulate efficiently, allowing mold to form.

 

AC Unit is too Big

Larger air conditioners can cool smaller spaces too quickly, causing the air to dehumidify before they switch off. As a result, extra moisture collects in the air vents and cannot be effectively circulated. It’s possible that your new unit is too big if you discover mold soon after it’s been installed.

 

Your Air Conditioner Is Too Cold

Do you have your air conditioner set to a low setting? Condensation can form in the room and on the air vents due to the temperature difference between the air conditioning and the room. Mold will form if this does not dry completely.

 

Does Mold on Air Vents Concern the Health?

If you notice mold growing on your air vents, don’t dismiss it. This can be extremely harmful, especially because the mold will be spread throughout your home by the air. You’ll start breathing it in, which can cause irritation in your eyes, nose, and/or throat; allergy symptoms such as runny nose, itchy eyes, or rashes; and headache, nausea, exhaustion, or dizziness whenever you’re inside the house.

You may have mold in your HVAC system if you, your family, or anyone who visits your house is suffering these symptoms. Please have the vents checked by a professional. These symptoms can appear in both healthy persons and those who have pre-existing diseases. If you find mold in your air vents and notice these symptoms suddenly, it’s time to clean them immediately. If your symptoms don’t go away, you should already see a doctor.

 

How Can Mold Be Removed From Air Vents?

 

Hiring a professional to remove mold from air vents is the best option. They will follow strict safety guidelines to ensure that they, your family, and your home are all safe. Furthermore, they utilize the proper cleansers that are both safe for your vents and effective against mold.

If this isn’t an option for you, we have a few alternatives that might work in the meantime.

 

Using Laundry Detergent 

  1. Regardless of which method you choose, you’ll need a few specific tools to remove mold from vents. These will keep you from inhaling or coming into contact with mold. When removing mold from air vents and ducts, take precautions. To avoid spores entering your nose and mouth, you’ll need a face mask with a HEPA filter, as well as gloves for your hands. We recommend the Trend AIR STEALTH dust mask as a reusable respirator half mask.

  1. Before starting your project, make sure the furnace or air conditioning system’s electricity is turned off. Remove the vent grill from the ceiling and place it in a large basin with a few drops of laundry detergent. Make certain it’s completely submerged.

 

  1. While this is soaking, vacuum out any dust or debris from the air vents with a HEPA vacuum. Empty the basin and rinse the air vent after 15 minutes. Soapy water should be sprayed and wiped down the inside of your air vents.

 

  1. Now spray the inside of your air vents, the vent grill, and the areas around the air vents with disinfectant. This will aid in the removal of mold and bacteria. To get deep into the air vents, you may need to use a mop.

 

  1. Allow the air to dry completely. You can reinstall the vent grill once the area is completely dry. Everything that comes into contact with the mold, such as rags, clothing, and gloves, should be thrown away.

 

Cleaning Air Vents with Bleach 

  1. If you have a non-porous surface, you can clean your air vents with bleach. Simply follow the box instructions and put on safety gear.

 

  1. Combine one part bleach and 16 parts water in a mixing bowl. Depending on the packaging instructions, this could differ. You’ll want to set aside a portion of the solution for step six.

 

  1. Turn off your air conditioning or heating system and vacuum the air vents with a HEPA vacuum cleaner. The Atrix HEPA Backpack Vacuum comes with a variety of attachments, thus we recommend it.

  1. Scrub the air vents with a rag dipped in bleach solution. Remove the air vents and submerge them in the bleach solution.

 

  1. While this is soaking, clean the inside of the air vents with the bleach solution you set aside. Clean the inside with a clean rag dampened with the solution.

 

  1. Allow for complete drying. After about 15 minutes of soaking, scrub the vent totally clean with a scrubbing brush or rag. Before reattaching the air vent, make sure it is completely dry.

 

What We Propose

 

Mold can be eliminated by mixing one cup of bleach with one gallon of water, but chances are you won’t be able to reach the mold deep within the home’s ductwork. Instead, you may eradicate mold in air vents by following these steps:

  1. Have the substance you think is black mold tested to make sure it’s the right kind of fungus. With this simple test, you may avoid a potentially time-consuming and costly cleaning.
  2. Determine the source of the mold in your home. Mold growth can be aided by wet wall interiors and damp baseboards. Identifying and treating the mold’s primary cause will ensure that the problem does not recur.
  3. Examine the ductwork’s surrounding insulation. If the mold in your air vents has spread to the insulation around them, you’ll need to replace it.
  4. Hire a professional cleaner who has been certified by the NADCA to clean the interior of the air vents. Because poor mold removal can be a waste of time and money, you should choose someone with experience and specific knowledge in fungus removal.

 

Vents Need Replacements

 

These time-consuming cleaning techniques may only keep your air vents clean for a limited time. So, rather than going through them, you could just choose to replace the vents.

Of course, you’ll need to clean the vents’ interiors and the surrounding region as well. However, unscrewing your air vent grill and replacing it with a new one may be a smart idea, and perhaps the safest method.

 

How to Keep Mold Out of Air Vents

 

  • Mold growth inhibitors

To prevent mold regrowth in air vents, look for an EPA-registered mold growth inhibitor product. Follow the manufacturer’s instructions for optimal product use.

 


  • Replace the filters if necessary

Replace your HVAC filters on a regular basis.

 

  • Make sure the drip pans are clean

Mold can easily form where the drip pans collect water. To avoid this, make sure to clean your drip pans on a regular basis.

 


  • Dehumidify the area

Reduce the amount of dampness in your home. You should get a decent dehumidifier and maintain it near any areas where mold can grow.

 

  • Inspections on a regular basis

You should get your ventilation system inspected on a regular basis by a professional provider. This ensures that there are no leaks, mold regrowth, or other flaws that could cause mold and mildew to grow. These companies may also clean and maintain the air vents to keep them in good working order.

 

  • Cleaning on a regular basis

Before mold appears, make sure you clean your air vents and ducts on a regular basis. You may keep them clean using the ways listed above so that they don’t become a breeding ground for mold.

 

  • The path must be cleared

Do not block your air vents with objects or barriers. This prevents proper air circulation, which can lead to the growth of mold.

 

  • Use UV light or ionization air purifiers to purify the air

Mold, viruses, and bacteria are all killed by these materials. To get rid of odors, mold, and other nasties, have these placed in your HVAC system — such as the coils or fan units. REKO Lighting R2000 Air Purifier and Germ Guardian AC4300BPTCA are highly recommended.

 

Key Takeaways

Finding mold development on your property, such as in vents, is never a good thing, especially when it comes to your health. Fortunately, you may use these methods to get rid of them and prevent them in the future. Incorrect mold removal procedures, on the other hand, might exacerbate the situation by spreading the mold and causing more harm. Some mold infestations are simply too much for an untrained individual to handle.
